Abstract

Angiolymphoid hyperplasia with eosinophilia (epithelioid haemangioma) is an uncommon but distinctive lesion seen principally in the skin. A case of severe gastrointestinal haemorrhage in a 63 year old male is reported, which necessitated a right hemicolectomy. A lobulated nodule was seen macroscopically that had the histological appearance of angiolymphoid hyperplasia with eosinophilia, with sheets of lymphocytes and eosinophils associated with many vessels showing plump and pleomorphic endothelial cells. This is the first reported case of this entity in the large intestine.
